Did you know colorectal cancer is one of the most preventable cancers when caught early?
The good news? You have options when it comes to screening. The best test is the one that gets done. ❤️
🩺 Colonoscopy (Every 10 Years)
Often considered the “gold standard,” colonoscopy can both find and remove precancerous polyps during the same procedure. It offers the highest protection against developing colon cancer because it can prevent cancer before it starts.
💡 Stool DNA Testing (Cologuard®) (Every 3 Years)
This at-home test looks for abnormal DNA and blood in your stool. It’s highly effective at detecting existing colon cancer but is less effective at finding precancerous polyps. A positive result requires a follow-up colonoscopy.
🏥 CT Colonography (Virtual Colonoscopy) (Every 5 Years)
A specialized CT scan creates images of the colon without sedation. It is very good at detecting larger polyps and cancers, but any abnormal finding still requires a traditional colonoscopy for removal or biopsy.
🩸 Blood-Based Screening (Guardant Shield®) (Every 3 Years)
The newest screening option requires only a blood draw. While convenient, it is currently less effective at finding precancerous polyps compared with colonoscopy, stool testing, or CT colonography. It may be appropriate for patients who would otherwise avoid screening altogether.
📅 Which Screening Test Is Right for You?
Factors that influence the best choice include:
• Your age
• Family history of colon cancer
• Personal medical history
• Risk factors
• Your preferences and comfort level
❤️ The most important message: screening saves lives. Whether it’s a colonoscopy, stool test, CT colonography, or blood test, getting screened is far better than not getting screened at all.
Current guidelines recommend that most adults begin colorectal cancer screening at age 45. If you have a family history of colon cancer or other risk factors, you may need to start earlier.
